Musical attack!
In fact, it tests more of one's 'Concentration', rather than 'Power'.
Huang Yaoshi tested Guo Jing and Ouyang Ke with the "Sea Waves Raising Song". Although Guo Jing's Inner Strength wasn't as strong as Huang Yaoshi's, due to his strong Concentration, he remained unharmed.

Of course, if one's Inner Strength surpasses that of the player, they can also remain unharmed.

Inner Strength is lacking!
Only Concentration can make up for it!
